Factual error: In the flashback where Otto gets on the train with Sonia, you can see the familiar Pennsylvania Railroad red keystone logo on the side of the railcar (or engine). The scene is approximately year 1972 (born 1955 from tombstone; Army physicals were age 17/18), and stated as in Pittsburgh. His ticket was $1.10, implying a short ride. But PRR ended commuter service in Pittsburgh in 1964. Moreover, PRR was merged into NY Central in 1968, so by 1972, the logo would have been Penn Central's green "PC."

Other mistake: If Otto's wife was in a wheelchair for 40 years, why did the house not appear to be handicap accessible? Otto hadn't touched anything in the house after her death, but the only noticeable building alteration was the low counter top in the kitchen. No permanent ramps? No stair lift?
